Look at lines PR←→ and ST←→ shown. Suppose a dilation with a scale factor of 2 and a center of dilation at point P is performed on QR¯¯¯¯¯¯¯¯ and ST¯¯¯¯¯¯¯. Which statements are true about the resulting images Q′R′¯¯¯¯¯¯¯¯¯¯ and S′T′¯¯¯¯¯¯¯¯¯¯? Select all that apply.
1. QR and Q′R′ are collinear.
2. ST and S′T′ are collinear.
3. QR and Q′R′ are not collinear, but are on parallel lines.
4. ST and S′T′ are not collinear, but are on parallel lines.
5. The measure of the length of Q′R′ is two times the measure of QR
6. The measure of the length of S′T′ is one half the measure of ST
7. If a segment is drawn from point P to point Q′, point Q will be the midpoint.
8. If a segment is drawn from point P to point S′, point S will be the midpoint.

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

median- 36f

mode - none

mean- 33.7 ~ 34f

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins
